Synthesis of Nickel Nanowires
It's all about the scale—they're not just wires, they're nanowires! The second lesson of the series builds on the oxidation-reduction experiment in the first lesson. Scholars synthesize a sample of nanowires using electrolysis. As they...
Curated OER
EggCELLent Diffusion
Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.

Fruit Cup DNA Extraction From Kiwi
Pupils extract DNA from kiwi using household equipment and supplies.
Curated OER
Mycorrhiza
Students examine the symbiotic relationship between fungus and plants. In this ecosystem lesson students complete several mycorrhiza experiments.
Curated OER
Body Organization and Organ Systems
Eighth graders begin the activity by building a house of cards. They discuss ways that building a house of cards is similar to the way the body is built: different systems work together to help the whole body work together. Students...
Curated OER
Blood Tonic
Students investigate the process of osmosis using fresh potato cuttings in saline solution. In this biology lesson plan, students explain the difference between hypertonic, hypotonic, and isotonic solutions. They collect data from the...
Curated OER
DNA Extraction
Students participate in a lab activity in which they extract DNA from a strawberry. After mashing the strawberry into an even, smooth puree inside a bag, they add extraction buffer and mix the strawberry with the buffer. They filter...
Curated OER
DNA Extraction
Students extract the DNA from a strawberry. In this DNA technology lesson, students describe what they think DNA looks like. They use a procedure to isolate and extract the DNA from a strawberry.
Curated OER
Pre-Hardy-Weinberg
Students examine the inheritance of ABO blood groups. In this investigative lesson students perform a lab and show how natural selection can alter the gene frequencies in a population.
Curated OER
Strawberry DNA Extraction
Students explore the DNA of strawberries. In this science lesson, students extract the DNA of strawberries. Students complete a lab report.
Curated OER
Life in a Mini World
Sixth graders observe, describe, and classify microorganisms found in water sources. In small groups, they make their own slide, observe the Protozoa under a microscope, and record and classify the microorganisms.
Curated OER
Protein Synthesis Activities
Learners compare the process of protein synthesis in an analogy. They simulate the process of protein synthesis kinesthetically using index cards and write a paragraph to explain the process.
Curated OER
Multiple Alleles
Students observe models of the ABO blood system including erythrocytes, antigens, and antibodies. They investigate the antigens that result from certain allele combinations and move antibodies to determine whether agglutination occurs...
Curated OER
Diffusion
Students develop the concept of diffusion. In this science lesson plan, students demonstrate diffusion of molecules of matter in various states.
Curated OER
From One End to the Other
Seventh graders become more familiar with how our food is broken down mechanically and chemically. They also trace the food through the alimentary canal.
Curated OER
When Microbes Attack
Learners study how the body defends itself against the invasion of harmful microbes and how certain types of drugs can provide assistance. They design and execute their own experiments to test whether increasing the number of types of...
